Input-field with captured text falsely empties on click

The script captures body-text to a specified input-field by either left-clicking and dragging the mousepointer over or simply performing a double-click on it.

The problem: When text is entered manually into the input-field, it simply disappears when a neighbouring select-element is clicked. Why?

Another minor issue is that I would actually prefer to be able to limit the capturable area to a container with an id.

Although this code doesn't make use of a framework, I wouldn't mind a solution with JQuery or MooTools.

Code:

// Captures highlighted text within the document to a specified input-field.
var text = "";

// Captures all highlighted text.
function captureText() 
{ 
	// Sets text MSIE or Netscape active.
	lookuptext = (document.all) ? document.selection.createRange().text : document.getSelection();
	
	// Form name="research", input name="lookup"
	document.research.lookup.value = lookuptext;

	return TRUE;
}

// Initiate capture function
document.onmouseup = captureText;
if(!document.all) document.captureEvents(Event.MOUSEUP);
